Application filed January 14, 1910, Serial No. 538,031. RenewedSeptember 19, 1913. Serial No. 790,730.

To all whom it may concern.

Be it known that I, Gusravn A. Sormnrrun, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented a certain new and useful Improvement in ElectricMeters, of which the following is a full, clear, concise, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to an improved form of electricity meter adapted tomeasure a quantity of electricity flowing through any given circuit.

My improved meter construction provides for accuracy of operation, easeof inspection and repair and durability of working parts.

My invention consists particularly in an improved form of lifting devicefor raising the movable armature of a meter of the class described fromits lower bearing, which is particularly to be desired in connectionwith shipping the meters. The lifting mechanism is operated by a screwwhich, when it is desired to lift the armature, is turned in against thelifting member as far as a shoulder formed on the screw will permit, asa result of which no judgment need be exercised to determine whether thearmature has been properly lifted or not.

The several drawings illustrating my invention are as follows:

Figure 1 is a longitudinal sectional View through the shaft 2 and showsthe lifting device in a position to raise the armature shaft from itslower bearing. Fig. 2 is a detail view of the magnetic shield 20 showingthe slot formed therein to permit the insertion and removal of thearmature shaft.

Similar numerals refer to similar parts throughout the several views.

As shown in the drawings, the base 1 supports the lower end of anarmature shaft 2 by means of a lower bearing 3. The shaft 2 carries nearits lower end a disk 5 of nonmagnetic material disposed between thepoles of a permanent magnet 6 held in proper position by the bracket 8secured to the base plate 1. Main supporting posts 18 extend outwardlyfrom and are rigidly secured to the base plate 1 and by means of arms 19support a magnetic shield 20 be tween the permanent magnet 6 and themeter windings.

The lower bearing 3 is secured to the base plate 1 by means of screws84; one of which extends through the lower bent end of a flat spring 85,the upper end of which is slotted as indicated at 86 in Fig. 1 to passaround the armature shaft 2. The spring 85 is so formed that it normallyrests below the hub 5 of the disk 5 when the shaft 2 rests upon itslower hearing. A screw 87 is threaded through the lower bearing support3 to engage the spring 85 to move it from its normal position upward toa position engaging the hub 5 to raise the armature shaft 2 from itslower bearing so as to protect such lower bearing for purposes ofshipping. The screw 87 is provided with a shoulder 87 so located thatwhen the screw is turned through the lower bearing support 3 as far asit will go, the spring 85 is moved against the hub or collar 5 withsufficient force to positively prevent jar of the instrument in shippingfrom damaging the lower bearing of the shaft. In this position a collar88 secured to the shaft 2 by means of a set screw as indicated andhaving a rounded upper end engages a countersunk opening 89 in the plate20 which opening is somewhat larger than the slot 20 formed in the upperportion of the plate 20 to permit the insertion and removal of thearmature shaft 2. As a result upward movement of the armature shaft isprevented beyond a certain point by the collar 88, and for this positionof the parts the armature shaft is held in its normal position eventhough the lower supporting bearing is removed.

The bearing support 3 has threaded therethrough a sleeve 56 adapted toreceive at its upper end, the lower end of the armature shaft 2, abearing 57 upon which the lower end of the shaft 2 rests is inserted inthe lower end of the sleeve 56 and held in place by a spring 59 securedto the support 3 by a screw 60. A hole 62 is formed in the spring 59 tobe engaged by a pin 61 secured in the support 3 when the spring 59 is ina position to hold the bearing 57 in place in the sleeve 56. While Ihave shown the detailed construction of this hearing in the presentapplication. it is not claimed herein as it forms the subject matter ofa copending application, Serial No. 538,028 filed January 14, 1910.

lVhile I have shown my armature lifting mechanism in the particularembodiment PatentedDec. 3Q, 1913.

herein described, I do not, however, limit myself to this exactconstruction but desire to claim any equivalent that may suggest itselfto those skilled in the art.

What I claim is:

In an electric meter the combination of a base, an armature shaft, aretarding disk carried by the shaft, a retarding magnet, a lower bearingfor the shaft a bracket for supporting such bearing, a lifting springnormally out of engagement with the disk and shaft a screw threadedthrough the bracket for engaging the spring to move it up against thedisk to lift the shaft from its lower bearing, an adjustable collarsecured to the shaft above the disk and conically shaped at its upperend, and a plate supported from the base and provided with an opening toreceive and engage the upper end of the collar when the shaft is liftedfrom its lower bearing.

In witness whereof, I hereunto subscribe my name this 28th day ofDecember, A. D.
